Encapsulate components by restricting their access modifier

[TonyTroeff]

Pull Request Description

There are a lot of publicly exposed components that cannot be easily modified because of breaking changes. In order to resolve this issue, we have decided to restrict their access from public to internal. Tests will still be able to access them, however.
